I had almost exact the same problem with v7 too: IM/P2P Settings - Controlled Networks: Internal, P2P Control: Block all, Exceptions: none, Advanced - Control skip-list: one host who should be able to use torrent. If I try to download a .torrent file the connection times out. In v7 the IM/P2P Classifier log showed a P2P Rule: Bittorrent block but in v8 not any more. If I disable the P2P Control, download a .torrent file, enable the control again and then start the torrent client the download works, so it seems the exception works but somehow the .torrent files can't get through ASG.
Can you give us a little more information: What software do you use to download the .torrent file, what software do you use as the torrent client, on what platform, what url do you download the .torrent from?
